benlisquare posted a topic in Off TopicNot that long ago, I made this post which reported on the extremely high GPU temperatures that I was getting while playing World of Warships, specifically in regards to the main port screen. At the time, my GPU became as hot as 86 degrees Celsius at the port screen, and 81 degrees Celsius while in battle. Fearing that one day the silicon components of my computer would melt or burn up in flames, I decided that it was about time that I replaced the thermal paste for the CPU and GPU. And so, I purchased a tube of Arctic Silver 5 thermal paste, and began to disassemble my laptop. Disassembly Removal of the keyboard panel, after removing the screws behind the back plate holding it in place. Removal of the LCD screen, giving access to the screws needed to remove the motherboard. Removal of the motherboard from the laptop unit. Motherboard of the ASUS G75VW, with CPU and graphics card heat sinks attached. Note the buildup of dust, over the span of 3 years. Other side of the motherboard, showing where the CPU and graphics card heatsinks attach on to the motherboard, and the location of the screws. The disassembled keyboard panel (left) and LCD screen (right). Miscellaneous parts disassembled from the laptop (optical drive, HDD, SSD, fan covers, etc.)
1. Description The game client uses an excessive amount of GPU resources while displaying the home port screen, to the point where the GPU overheats and reaches extremely high temperatures. In fact, the port screen uses more GPU resources than actual in-game battles; the GPU fan speed and temperatures happen to be markedly lower whilst in-battle compared to at the port screen. Currently it is winter in Australia, however during the summertime this may potentially cause housefires if players leave the game running for long time durations, idle at the home port screen. In addition, I'd presume that players with high-end nVidia cards would have a much more severe circumstance compared to mine, and this is also likely to be the case for people who have much more poorly ventilated machines compared to mine. 2. Reproduction steps Run the game, leave the game sitting idle within the home port screen for long durations of time, record GPU temperatures. 3. Result The following temperature chart shows the changes in GPU temperature whilst in-battle, for comparison purposes. Units are in degrees Celsius. The battle begins immediately after the sharp dip from 60 degrees Celsius (at the time when the game was minimised and the Windows desktop was displayed), and reaches an average temperature of 81 degrees Celsius during the battle. The following temperature chart shows the changes in GPU temperature whilst left idle in the home port screen. Units are in degrees Celsius. The time period spent within the port screen is immediately after the second dip; for comparison purposes, the period directly preceding the dip is the in-battle temperature shown earlier. Whilst at the port screen, the temperature reached a maximum value of 86 degrees Celsius before I ALT+TAB-ed to desktop to take a screenshot of the temperature reading. Had I not done so, the temperature would have continued to rise, given that the upward parabolic curve has yet to fully plateau. 4. Expected result The port screen should not overutilise GPU resources, to the point where the GPU generates more heat at the port screen compared to actual battles. Given that players are often likely to leave the game running idle whilst at the port screen (e.g. looking for food/drinks), the GPU utilisation should be at least the same as a battle, if not less. 5. Technical details While testing the temperatures as described above, the following graphics settings were used: Dxdiag: http://pastebin.com/P2qnR9S0 Addendum: My computer has removable dust filters attached to the fans, and I clean them every two months.
